摘要
双红、双优和左优红掐除花序尖2/5并疏果粒,坐果率、果粒重和果实含糖比对照(CK)大幅度提高,但果穗重量大幅度降低而减产。双红和双优品种掐除花序尖1/5并疏果粒,坐果率、果穗和果粒平均重、果实含糖和产量与CK相比较效果不明显,无生产栽培效益。左优红为长穗散形大粒品种,掐除花序尖1/5并疏果粒后,果粒和果穗平均重及果实含糖都高于CK,效果明显,增产幅度大,适合在生产中推广应用。
Removal of 2/5 inflorescence tip and thinning fruit of Shuangyou、Shuanghong and Zuoyouhong had fruit setting rate、fruit weight and sugar content were significantly increased, but cluster weight greatly decreas than those of（CK）, hence caused yield reduction. Of that same treatment, fruit setting rate.cluster weight、fruit weight、suger content and production compared with CK were not obvious. It had no effect on production cultivation. Zuoyouhong had long cluster bulk shape big grain variety. Removal of 1/5 inflorescence tip and thinning fruit of Zuoyouhong, fruit weight、cluster weight and sugar content were higher than CK. The effect was evident on the range of yield output, so it is suggested to extend application in the production.
